Alinco almost got it right, at least with the DR599 and possibly the DR600. The radio can be remote controlled if it has the DTMF decoder option board via RF. I think you can also remote control it by applying the remote control DTMF tones to the mic input without keying the radio (I haven't tried but I think that's the way the DTMF mic sends commands to the radio). The only snafu is that they didn't include a provision for setting offset and the radio doesn't do it automatically. Now that I've found the book for mine, it may be time to do a little more investigating.

I would say that depends on when the radio was made. Older Yaesu's, such as the FT-757 and even the FT-727 had a "CAT" interface which allows data from a computer to set the operating parameters of the radio. Other radios in the Yaseu line, Such as the FT-5100 have a few lines for the buttons, like band sellect and channel up and down. Which can allow 'poor mans remote base'. Others take a serial data stream down the mic jack to do control of the radio. You would have to get a logic analyzer or digital storage scope to disect the protocol though.
